Again, this should be part of the regulator API code not hidden away
where it will only get reviewed by device tree people.

 Required properties:
 - compatible: Must be "regulator";
+or
+- compatible: Must be "regulator-fixed"; /* For Fixed volatge regulator */

This seems at best confusing - the fixed voltage regulator is a
particular regulator driver, and the general concept of a fixed voltage
regulator is still a subset of regulators.

+# For fixed voltage regulators
+- supply-name: Name of the regulator supply
+- microvolts: Output voltage of regulator
+- gpio: gpio to use for enable control
+- startup-delay: startup time in microseconds
+- enable-high: Polarity of enable GPIO, 1 = Active High, 0 = Active low
+- enabled-at-boot: 1 = yes, 0 = no

Much of this is specific to the Linux fixed voltage regulator driver
rather than a generic regulator with a fixed voltage.
